' INDICATING AND REGISTERING :MECHANISM FOR/ TANKS.

To' all whom itlmag concern 1 Be it known thatI, ADAM M. WOLF, a citizen of the United States, residing at Plymouth, in the county of Shebo-ygan and State of Wisconsin, have'invented a new and use ful Indicating and Registering Mechanism for Tanks, of which the following is a specification.

This'invention relates to' improvements in mechanisms for indicating and registering the quantity of a liquid supplied to and dc livered from a'tank. An'object of the presentinvention is to provide a mechanism for "registering the quantity of liquid flowing through and re-.

, maining in a tanlgand which mechanism automatically prevents the supply of a liquid to the tank in excess of the capacity thereofi.

A further object is to provide an indicatmg arm moving over a graduated scale, the

clockwise reading of which indicates the quantity of liquid within a tank and the anti-clockwise reading of which taken from s-zrme arbitrary point, indicates the quantity. of liquid discharged from the tank, the said.

arbitrary point representing the quantity of liquid within the. tank prior to the discharge of the liquid therefrom'the volume of which 'discha rge it is'dcsired to'determine.

A further object is to provide a register- .ing mechanism with a scribable surfaceand a marker moving ther'eover, thus automatically recording the quantity of aliquid supplied to a tank .and the amount-discharged therefrom. y

A further objectis to provide a registering and indicating. mechanism in which an indicating arm is provided with plurality of ofi'set extremities. In reading the scale that extremity is used which corresponds to the specific gravity of theliquid within the tank.

With the foregoing-and other objects 'in View which will appear as the description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, 'it being understood that changes in the precise embodiment of the invention herein disclosed; can he made within the scope of what is claimed, without departing from the spirit oi the invention. In the drawings accompanying tlns speci- ,fication and forming a part thereoI, the preferred embodiment of my invention is illustrated, in which trated in Fig. 4, is curled'or'ben't u as-at l2 and rotatably receives thet pi'n 13 V Eigure l-is a view in section ofa tank with my Improved ind cating and recording pecification of Letters Patent.

mechanism ailixed thereto. ,Fig. 2 is a cross sectional view taken on the linej22 of Fig.

3 is a top plan view of the float employed in connection with the foregoing. Fig. 4 is a fragmental view in section of the lower extremity of the float carrying arm. Fig. 5 is a top plan view of a' somewhat ,modified form of mechanism. Fig. Gisa' fragmental view in section of themodifica tion. Fig. 7 is a fragmental detail'view'of the multl-indlcating arm.

Referring to the drawings in which simi 'lar reference numerals designate correspond ing parts throughout the several views, a

tank 7- is provided with the inlet openingS through which a liquid may be introduced for the filling of the tank. Secured tofone' wall of the tank is the upright or'standar'd 9 which is adapted to support the actuating portions of the mechanism herein described, .A hearing member 10 projects laterally from the standard 9, to which is pivotally secured a float carrying-arm 11. The lower extrem ity of. the float'carrying arm 11, as illus- 'therein, the, said pin extending-across the slot 1- with which the float 15 is provided.

The length of the float carrying lever or arm 11 is such that when the tank is filled. the

n itself float will assume the position indicatedby dotted lines in Fig. 1, closing the inlet 8 and preventing-the further supplyof the liquid to, the tank.

a 'An outstanding bearing is carried by the standard 9, through which extends the shaft- 1'7 the latter being journaled through the side wall as at 18, effecting a rotatable but liquid-tight'joint therewith. 'A crank arm 19 is rigidly secured to the shaft 17 and oscillates the same through the-intervention of the link20. Thelink 20 is pivotally secured as at 21 to thefl-oat carrying lever 11;

so. that movements of the float will'result in the rotationof the shaft'lT. t Rigidly secured to the tank 7 is the casing 21, the latter receiving the extremity of the shaft 17 ther'ein', upon which, shaft and ex- 'ternal of the tank, s mounted the indicating arm '22. "The casing 21'is provided with the door 23, the same having the glass panel Atherein. To the rear portion of the case} ing is secured the scribable member25, ,thej same being ofslate or allied material, upon.

The uppermost scale 28 reads in a clockwise directiom while the inner scale 29 is reversely 311'? ranged. scrihing member- 30 is carried v by the indicating arm'and draws a line upon the in inber 25, to thus form a temporary record of tie 1 h g the modified forms illustrated, in Figs.

The said scaie isjvisible from above through the transparent member 37 as Illustrated in Fi r "lhe operatien of the mechanism Will be readily understood, the float moving, the,

from A to" B. This will therefore indicate the quantity of liquid-discharged from the tank. After the said quantity has been discharged, a quantity may be introduced which will Q then draw the line -BC' or B--C inasmuch as the point A Was noted at the time the lines Were previously erased, the quantity of liquid drawn from the tank and sub quently introduced therein, may be read A. -l? The line AB in terms of the lower. scale 25), indicates the quantity of liquid witl'idrawn from the tank so that line B C or l?'C in terms ofthe upper scale 28, de-

' termines' the quantity of'liquid introduced \i'ithinthe tank. After the line B-C has been drawn or traced, the lines are erased, after which the liquid in the tank may be withdrawn as desired. -The 'pointed end 26 lheindicating arm termithe extent of moven1ent of the" I determined regardless of Whether C falls internally or exteriorly of the points readv upon the top scale, indicates the .itity of liquid Within the tank and as. determiiu-d upon the bottom scale indicates the quantity of liquid which may be introduced ithin the tank in order to completely fillthesame.-

.The indicating ar1n50 as illustrated in Fig. 7, is provided With a number of indicating fingers 51 which are oifset one with relation to the other and are readable ubon the scales 52, 53 and 54. The different scales 52, and 54 are plotted'and the in- "d-icating fingers 51-ar'e arranged so as to read correctly for different grades of oil or other liquid. Thus with an oil of relatiyely low specific gravity, one'of the indi cating fingers 51 is'takenas themeasure of the scale reading, While for a liquid of relatively high specific gravity, one ofthe other fingers will be employed.

Thelink connection is such that the readingis 111 a clockwise direction, the same being the-conventional direction for indicating instruments;
